Abstract:A design of photovoltai charging is proposed. Different modes of Maximum Power Point Tracking (MPPT) is adopted to control the output characteristics of PV in different sunlight intensity. During the strong sunshine, variable step incremental conductance algorithm is adopted for lithium batteries and super capacitor charging; During the weak sunshine, perturbation and observation algorithm is adopted for the super capacitor charging. Lithium battery is charging by the energy stored in the super capacitor. The design is achieved bythe system based on MSP430F5132, the results show that the design can efficiently use solar energy to charge lithium batteries.
